Exhibit 1.01

Conflict Minerals Report of MRV Communications, Inc.
In Accordance with Rule 13p-1 under the Securities Exchange Act of 1934

Introduction

MRV Communications, Inc., also referred to as “MRV”, “we”, “our”, and “us” is a provider of innovative network solutions for service providers, data center operators and enterprises.

This Conflict Minerals Report (“CMR”) for the year ended December 31, 2016 is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (the “Rule”). The Rule imposes certain reporting obligations on U.S. Securities and Exchange Commission (“SEC”) issuers whose manufactured products contain certain minerals which are necessary to the functionality or production of their products. These minerals are cassiterite, columbite-tantalite (coltan), gold, wolframite, and their derivatives, which are limited to tin, tantalum and tungsten (“3TG” or “Conflict Minerals”). The Rule focuses on 3TG emanating from the Democratic Republic of the Congo (“DRC”) region and nine adjoining countries (together, the “Covered Countries”). If an issuer has reason to believe that any of the Conflict Minerals in their supply chain may have originated in the Covered Countries, or if they are unable to determine the country of origin of those Conflict Minerals, then the issuer must exercise due diligence on the Conflict Minerals’ source and chain of custody and submit a CMR to the SEC that includes a description of those due diligence measures.

This CMR relates to the process undertaken for MRV products that were manufactured, or contracted to be manufactured, during calendar year 2016 and that contain Conflict Minerals.

Executive Summary

MRV performed a Reasonable Country of Origin Inquiry (RCOI) on suppliers believed to provide MRV with materials or components containing 3TGs necessary to the manufacturing of MRV’s products. MRV’s suppliers identified 319 valid smelters and refineries (“smelters”). Of these 319 smelters, MRV identified 37 as sourcing (or there was a reason to believe they may be sourcing) from the Covered Countries. MRV’s due diligence review indicated that 33 of these smelters have been audited and recognized as conflict free by the Conflict Free Smelter Program (“CFSP”). The remaining 4 smelters were subject to MRV’s risk mitigation process according to the Organisation for Economic Co-operation and Development (OECD) Due Diligence Guidance for Responsible Supply Chain of Minerals from Conflict-Affected and High Risk Areas (OECD Due Diligence Guidance).

Company Management Systems

MRV established strong management systems according to Step 1 of the OECD Due Diligence Guidance. MRV’s systems included

• Step 1A - Adopt, and clearly communicate to suppliers and the public, a company policy for the supply chain of minerals originating from conflict-affected and high-risk areas.

• Implemented a conflict minerals policy

• Policy made publicly available

• http://mrv.com/company/quality-regulatory-compliance/

• Policy communicated directly to suppliers as part of RCOI process

• Step 1B - Structure internal management to support supply chain due diligence

• Maintained an internal cross functional team to support supply chain due diligence

• Appointed a member of the senior staff with the necessary competence, knowledge, and experience to oversee supply chain due diligence

• Applied the resources necessary to support the operation and monitoring of these processes including internal resources and external consulting support.

• Step 1C - Establish a system of transparency, information collection and control over the supply chain

• Implemented a process to collect required supplier and smelter RCOI and due diligence data. Full details on the supply chain data gathering are included in the RCOI and due diligence sections of this Report.

• Step 1D - Strengthen company engagement with suppliers

• Directly engaged suppliers during RCOI process.

• Reviewed supplier responses as part of RCOI process.

• Added conflict minerals compliance to new supplier contracts and MRV’s supplier code of conduct.

• Implemented a plan to improve the quantity and quality of supplier and smelter responses year over year.

• Step 1E - Establish a company and/or mine level grievance mechanism.

• Recognized the CFSP’s three audit protocols for gold, tin/tantalum, and tungsten as valid sources of smelter or mine level grievances.

• MRV’s ethics violations reporting system allows employees to voice confidentially without any fear of retribution, any concerns with the violations of the MRV’s conflict minerals policy

Reasonable Country of Origin Inquiry (RCOI)

MRV designed its RCOI process in accordance with Step 2A and 2B of the OECD Due Diligence Guidance. MRV’s RCOI process involved two stages:

• Stage 1 - Supplier RCOI (Step 2A of the OECD Due Diligence Guidance)

• Stage 2 - Smelter RCOI (Step 2B of the OECD Due Diligence Guidance)

Supplier RCOI

MRV designed its supplier RCOI process to identify, to the best of MRV’s efforts, the smelters in MRV’s supply chain in accordance with Step 2A of the OECD Due Diligence Guidance. MRV’s supplier RCOI process for the 2016 reporting period included the following -

• Developing a list of suppliers providing 3TG containing components to MRV

• Contacting each supplier and requesting the industry standard Conflict Minerals Reporting Template (“CMRT”) including smelter information.

• Reviewing supplier responses for accuracy and completeness.

• Amalgamating supplier provided smelters into a single unique list of smelters meeting the definition of a smelter under one of three industry recognized audit protocols.

• Reviewing the final smelter list (and compared it to industry peers) to determine if MRV identified reasonably all of the smelters in their supply chain.

For the 2016 reporting period, MRV’s RCOI process was executed by Claigan Environmental Inc. (“Claigan”).

MRV’s suppliers identified 319 smelters in their supply chain. The specific list of smelters is included in the Smelter and Refineries section at the end of this report.

Smelter RCOI

Due to the overlap between supplier RCOI and smelter due diligence, the smelter RCOI process is summarized in the due diligence section of this report.

Due Diligence

MRV’s Due Diligence Process was designed in accordance with the applicable sections of Steps 2, 3, and 4 of the OECD Due Diligence Guidance.

Smelter RCOI and Due Diligence

MRV’s smelter RCOI and due diligence process were designed to

• Identify the scope of the risk assessment of the mineral supply chain (OECD Step 2B).

• Assess whether the smelters/refiners have carried out all elements of due diligence for responsible supply chains of minerals from conflict-affected and high-risk areas (OECD Step 2C).

• Where necessary, carry out, including through participation in industry-driven programs, joint spot checks at the mineral smelter/refiner’s own facilities (OECD Step 2D).

MRV’s smelter RCOI and Due Diligence Process included the following -

• For each smelter identified in MRV’s supply chain

• MRV attempted direct engagement with the smelter to determine whether or not the smelter sources from the DRC or surrounding countries

• For smelters that declared directly (e.g. email correspondence, publicly available conflict minerals policy, or information available on their website) or through their relevant industry association that they did not source from the DRC or surrounding countries, and were not recognized as conflict free by the CFSP, MRV reviewed publicly available information to determine if there was any contrary evidence to the smelter’s declaration. The sources reviewed included

• Public internet search (Google) of the facility in combination with each of the Covered Countries

• Review of specific NGO publications. NGO publications reviewed included

• Enough Project

• Global Witness

• Southern Africa Resource Watch

• Radio Okapi

• The most recent UN Group of Experts report on the DRC

• For smelters that did not respond to direct engagement, MRV reviewed publicly available sources to determine if there was any reason to believe that the smelter may have sourced from the Covered Countries during the reporting period.

• MRV reviewed the same sources as those used to compare against smelter sourcing declarations.

• For high risk smelters (smelters that are sourcing from or there is reason to believe they may be sourcing from the Covered Countries), MRV requires the smelter be audited and recognized as conflict free by the CFSP.

• For high risk smelters that have not been audited and recognized as conflict free by the CFSP, MRV communicates the risk to a designated member of senior management (OECD Step 3A) and conducts risk mitigation on the smelter according to OECD Step 3B.

For the 2016 reporting period, MRV’s smelter RCOI and Due Diligence process was executed by Claigan Environmental Inc. (Claigan).

MRV’s suppliers identified 319 smelters. MRV identified 37 smelters that source, or there is a reason to believe they may source, from the Covered Countries.

MRV determined that 33 of these 37 smelters have been audited and recognized as conflict free by the CFSP. MRV conducted risk mitigation on the remaining 4 smelters.

Risk Mitigation

MRV conducted risk mitigation on 4 smelters that were not recognized as conflict free by the CFSP. MRV’s risk mitigation was designed in accordance with Step 3B of the OECD Due Diligence Guidance and was reported to the Vice President of Operations, in accordance with Step 3A of the OECD Due Diligence Guidance. MRV’s risk mitigation process included the following -

• Additional due diligence to determine if there was any reason to believe the smelter directly or indirectly finance or benefit armed groups in the DRC or adjoining countries.

• Verifying with internal stakeholders and relevant suppliers whether 3TGs from the specific smelter were actually in MRV’s supply chain in the 2016 reporting period.

• Direct engagement with the high risk smelter to verify risk and to encourage the smelter to become conflict free.

Risk mitigation was required for 4 smelters verified by suppliers likely to be in MRV’s supply chain. MRV is currently working with its suppliers to mitigate identified risks.

Improvement Plan

MRV is taking and will continue to take the following steps to improve the due diligence conducted to further mitigate risk that the necessary conflict minerals in MRV’s products could directly or indirectly benefit or finance armed groups in the Covered Countries:

a. Including a conflict minerals clause in all new and renewing supplier contracts.

b. Continuing to drive our suppliers to obtain current, accurate, and complete information about the smelters in their supply chain.

c. Engaging smelters sourcing from the Covered Countries to be audited and certified to a protocol recognized by the CFSP.

d. Follow up in 2017 on smelters requiring risk mitigation, but not removal from MRV’s supply chain.
